Title: Improvements relating to brake testing equipment for vehicles
Inventor: DOUGLAS ROBERT STODDART
IPC: G01L5/28
Filed: 1959-02-26
Abstract: 883,534. Brake testing. TRIANGLE PRODUCTS Ltd. Feb. 26, 1960 [Feb. 26, 1959], No. 6634/59. Class 106 (2). The pressure fluid which indicates at 7a the torque applied to a roller 4 in order to rotate a wheel (e.g. of a motor cycle) against the resistance of its brake, applies through a capsule 12, a downward force to one end of a lever 10 until a platform 11 at the other end of the lever just lifts the wheel; and the brake efficiency and the axle weight of the vehicle can then be simultaneously indicated through the same fluid system, as by providing two scales at 7a with a common pointer, or two indicators simultaneously operated. The torque is transmitted by a gear-box 6 which tends to rotate bodily until the brakes yield and, in so rotating, increases the pressure in the fluid.
Patent GB-882787-A (GB)
Title: Cabin pressurization system using a-c power
IPC: G05D16/20
Filed: 1958-03-03
Abstract: 882,787. Automatic pressure control systems. KOLLSMAN INSTRUMENT CORPORATION. March 3, 1958 [March 19, 1957], No. 6710/58. Class 38 (4). In a system for maintaining the pressure in a pressurized cabin at a desired value, air is supplied to the cabin under pressure and an exhaust valve for the cabin is automatically adjusted by a reversible A.C. motor under the control of A.C. signals responsive to cabin pressure and rate of change of cabin pressure. In Fig. 1, when cabin pressure deviates from a value determined by the setting of a knob 54 adjusting the bridge-type variable inductive pick-off 36 of a bellows 30 responsive to cabin pressure, A.C. signals are produced which are opposed to A.C. signals from the pick-off 34 of a bellows 28 responsive to rate of change of cabin pressure and applied to an amplifier 60, the output of which controls a two-phase reversible motor 62 adjusting a cabin exhaust valve 20 to correct the deviation. The signals from pick-off 36 reach a maximum value for small deviations of cabin pressure so that motor 62 operates to change cabin pressure at a rate corresponding to that maximum value which is adjustable manually by a potentiometer 56 controlling the energization of pick-off 36. The signals from amplifier 60 also control a motor 80 adjusting a second exhaust valve 21 for the cabin and the two exhaust valves are synchronized by further controlling motor 80 by the output of an amplifier 78 to which is applied synchronizing error signals developed by selsyns 70 and 74 associated with valves 20 and 21 respectively. A.C. signals produced by pick-off 38 of a bellows 32 when the difference between cabin and external pressure exceeds a predetermined value are also applied to amplifier 60 and they are of such magnitude and sense as to ensure movement of the valves to an open position to prevent undue stress on the cabin. Energization of relay 64 when the landing gear is operated prior to landing introduces a fixed A.C. voltage from potentiometer 68 in opposition to the signal from rate bellows 28 so that cabin pressure is equalized with external pressure at a predetermined rate. The pressure transducers are of the type described in Specification 882,786 (see Group XXXVIII).

Abstract: 1,222,241. Determining distance to go. GENERAL ELECTRIC CO. 15 Feb., 1968 [9 March, 1967], No. 7500/68. Heading B7N. [Also in Division G1] In an arrangement for determining the distance between a fixed point on a railway track and a rail vehicle, e.g. for determining the distance to go in a hump-yard classification track, a bridge circuit is connected to the rails at the fixed point for determining the inductance of the loop formed by the track rails and the vehicle axle from which the distance is determined. The bridge, Fig. 1, has the track loop represented by inductance 10 and resistance 12 connected in leg TI, a fixed resistance 17 in leg FR, a combination of resistance 20 and capacitance 22 in leg RC and a variable step impedance 28 in leg RB. Resistance 14 compensates for lead length when the bridge has to determine the distance for a number of different classification tracks. A logic circuit including a 0-10 counter is provided for controlling the operation; at each count a short circuit is removed from a different impedance in the bridge leg RB. When the phase comparison of the voltages at points 16 and 26 indicates a phase difference in one direction the impedance is retained in the circuit, if the difference is in the opposite direction the last added impedance is again shorted out and the next lower value added at the next count. The impedances are calibrated in terms of loop distance and the sum of the impedances in circuit at the 9th count is an indication of the required distance. The tenth count restores the apparatus to zero.
